[PATCH v2 0/6] Improve test coverage of update-ref error messages

This is v2 of the patch series. Thanks to Johannes Sixt and Junio for their comments about v1 [1].

Changes since v1:

* In t1404, don't use non-portable `local`: change function
  test_update_rejected to refer to the global `$prefix` variable
  rather than taking it as a parameter.

* Because that code change has become more involved, split off the
  addition of documentation for the function into a separate patch.

These patches are also available from my GitHub account [2] as branch update-ref-errors.
